ALFRED GUSTAFSON, OF JUNCTION CITY, KANSAS.

SAW SET.

Application filed August 18, 1921. Serial No. 493,329.

To all whom it may concern:

Be it known that I, ALFRED GUSTAFSON, a citizen of the United States, residing at Junction City, in the county of Geary and have invented certain new and useful Improvements in Saw Sets; and I do declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

invention relates to improvements in saw'sets and more articularly to those of the type primarily Y esigned for setting ciroular saws, while not restricted however to this use.

In carrying out my invention, I employ a handle-carried shank having a fixed jaw at its front end, and a slide carrying a movable jaw is shiftable along this shank so as to bring the two jaws in operative relation with each other, re ardless of the thickness of the saw teeth. ne object of the invention is to provide the slide with an ad'ustable stop adapted to strike one side 0 the saw to limit the movement of the tool and consequently control the angle at which the saw teeth are set.

In mounting the slide upon the shank, the latter is formed with a longitudinal slot through which a clamping screw passes Eor holding said slide in adjusted position, and a further aim of the invention is to construct the above mentioned stop in such a way that one end thereof extends into said slot, so as to prevent pivotal action of the slide about the clamping screw.

Yet another object is to provide a novel means for receivin the rearward thrust of the slide, during tie action of setting the saw teeth.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the de scriptive matter being supplemented by the accompanying drawings.

Figure 1 is a side elevation of a saw set constructed in accordance with my invention.

tool showing its In the drawings above briefly described, the numeral 1 designates an appropriate handle provided with a rigid forwardly extending shank 2, the front end of said shank being provided with a laterally extending fixed jaw 3 which is preferably arranged obliquely as shown. The shank 2 is provided with a longitudinal slot 4 and in rear of this slot, one side of said shank is equipped with a fixed shoulder 5. An elongated slide 6 contacts with the shoulder 5 of the shank 2 and is provided at its front end with a jaw 7 parallel with the jaw 3 and adapted for coaction therewith in ripping the saw teeth as shown in Fig. 6. g clamping screw 8 passes through the slot 4 and is threaded in the slide 6 for frictionally binding the latter after it is adjusted according to the thickness of the saw teeth but in addition to this clamping means, I prefer to use a wedge 9 interposed between the shoulder 5 and the rear end of the slide 6, for the purpose of receiving the thrust of said slide. The wedge 9 extends transversely of the shank 2 and is provided with a slot 10 through which a screw 11 passes to clamp the wedge against movement when it is properly set.

The jaws 3 and 7 are engaged with the saw teeth in the manner shown in Fig. 6 and the h audio 1 is then moved toward the jaw, with the result that the teeth are bent to the required extent, and in order that all of the teeth may be uniformly set, I provide a stop pin 12 which is threaded diagonally through the slide 6, the front end of said pin being adapted to strike the saw as shown in Fig. 6, while the rear end of the pin is received in the slot 4 and thereby prevents pivotal movement of the slide 6 about the clamping screw 8, when the latter is loosened and the slide is being adjusted.

I have described the pin 12 as threaded through the slide 6, but it will be understood that it might otherwim pass adjustably through this slide. \Vhen the threaded formation is used, the front end of the pin is preferably provided with a flat-sided head 13 so that it may be readily turned for making the necessary adjustments and a winged lug nut 14 is threaded on said pin to bear against the slide and hold the former in adjusted position.

From the foregoing, taken in connection with the accompanying drawing, it will be seen that while my invention is extremely simple and inexpensive, it will be highly 7 however that within the scope of the inven pin extending a justab efficient and in every way desirable. Since contact with said shankand a jaw excellent results have been obtained from cooper-able with said jiw 7 7 ajnpin the details shown herein, these details are svrew passing through said slot for holding preferably followed.
